Answer:</u></h3>
Hence, the value of z is:
20
<h3><u>
Step-by-step explanation:</u></h3>
The point C is the mid point of the line segment VW.
That is it divides the line segment VW into two equal segments.
i.e. Length of segment VC= Length of line segment CW.
Also we are given that:
Length VW=61
Length VC=z+13
and Length CW=z+8
This means that:
VC+CW=VW
i.e. z+13+z+8=61
⇒ 2z+21=61
⇒ 2z=61-21
⇒ 2z=40
⇒ z=20
Hence the value of z is:
20
So we already drew two cards and both of them are spades. So that means there are 50 cards and 11 spades left.
Then third card being spades would be 11 / 50
Now there are 10 spades and 49 cards left.
So the probability for fourth card would be 10 / 49
Fifth card would be 9 / 48.
So the probability of next three cards being spades would be

Answer: If it is traveling at 0.15 miles per second, it's speed is 540 miles per hour.
Step-by-step explanation:
Use the unit multiplier 3600sec/hrtimes 0.15 mile/sec.
.0.15 × 3600 = 540. Sec cancels so we're left with a speed in miles per hour.

Answer:
c
Step-by-step explanation:
The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation
The average rate of change of a function f(x) on [a,b] is
We need to find the average speed of the car, in feet per second, between t=2 and t=5.
At t=2,
At t=5,
The average speed of the car, in feet per second, between t=2 and t=5 is
The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.
